IMPROVEMENT IN SHUTTER-CASES.

Specification formingpart of Letters Patent No. 49,4 ll, dated Augustl5, Lf'ti.

.To all whom 'it 'may concern; I

Be it known that I, JAMES INGRAM, ofthe city and State of New York, haveinvented, made, and applied to use a certain new and useful Improvementin Shutter-Cases; and I do hereby' declare the following to be a i'ull,clear, and exact description ot' the said invention, reference being hadto the annexed draw` ings, making part ot' this speeitication. wheren1-Fignrc 1 is a plan ot' my shuttereasc, and Fig. 2 is a vertical sectionot' said case.

Similar letters denote the same parts.

The shutters for the windows and doors of stores have heretofore usuallybeen contained in a case or box at the side ot' the store or stood up insome out-ottheway place during the daytitne. In this condition they aregenorally ex'posed to the action ot the weather and to other injury, andin eases where the shutters are lowered down into a stationary case inthe. sidewalk they are. often injured by being dropped sonic distanceinto the case.

The nature ot' my said invention consists in a slidingr shutter-easeacted on by a screw, so that the case can be lowered al'ter the shuttershave been placed in it, or raised previous to the shutters being takenout. of said ease. By this device tite shutters are entirely excludedfrom the action ot' theaveather and the handling of them facilitated, sothat they are not as liable to be broken as heretofore.

In the drawings, c isa frame ot' suitable size and shape, at the upperend ot' which is a flange, b, that is tobe set into the Hag-stone of thesidewalk, or level with the area or stone over the area, so that theframe a shall be entirely below and out ot' the way. Within the trame ais the slitting shutterease, formed ot' the bottom c and angle-pieces Zd, and these angle-pieces d d .are connected to each other by the barsor frame e.

ffare cross-pieces from the side bars ot" the sustain the screw g,collars heilig provided at t1', so that the screw q is kept in positionbetween the cross-pieces ff.

h is a cross-.bar from the trame a, carrying the nnt ofthe screw g, andi: is a similurcrossbar, acting as a guide to thel lower end of thescrew g.

It will now be evident that it t-he screw g is rotated in the stationarynut in /i the entire shutter-case will be raised or lowered, and with itthe. shutters that may be contained in it. These shutters arerepresented at l.

The screw q may be extended up, as shown at. I, and be operated by acrank-handle placed upon its upper end, or, it' the distance across istoo far to reach conveniently, the motion may be communicated from thecrank -m through the gears n., 0,1), and q,- or the shaft s, carrying`the gears o and p, may have a square at the end for the reception ot'said crank, so as to rotate the screw more easily when the sluitter-caseis partially raised.

The red lines in Fig. 2 illustrate the point n to which the shutter-casecan be lowered so as to be below the top of the frame a entirely, and acover is to be put over the whole, as shown by the red line at t.

The sliding shuttereasc may be provided with friction-rollers at the.angles, as seen at 1l u, and a coiniterpoisc maybe provided to aid inraising the shutters and case.

\Vhat I claim, and desire to secure by Letters Patent, is-

'l`he stationary trame a, below the sidewalk or other surface, incombination with the slid' ing shutter-case and screw, substantially asand t'or the purposes` specitied.

In witness whereof' I have hereunto se my signature this 28th day ot'hl'arch, A. D. I
